  • Publication number: 20220160440
    Abstract: A surgical robotic arm (520) for use with an external vision system (512) includes onboard control and at least four degrees of articulation. The robotic arm (520) can position various tools (534) in the surgical theatre responsive to positional feedback In from the vision system (512). Exemplary tools (534) include a handpiece (519) that includes a motorized bun or saw, a cutting guide (542) for a handheld saw, or a laser to actively define a resection area for a surgeon. The tool (534) or a reference point on the arm (520) relative to the tool (534) includes fiducial marks to register the position of the tool (534) with the vision system (512). Exemplary (534) are especially suited for knee and hip arthroplasty and can be moved under processor or manual control.

  • Publication number: 20210322148
    Abstract: A method of placing a ligament graft in a surgical procedure is described. A surgical system receives kinematic information related to a range of motion of a knee joint and registers one or more surfaces of a bony anatomy of the knee joint. The surgical system further generates a three-dimensional model of the knee joint. The surgical system determines a surgical plan including parameters of a graft tunnel based on the kinematic information and the three-dimensional model. A graft tunnel planning system is also described. A plurality of tracking markers are affixed to the patient's bones and a tracking unit captures their location through a range of motion of the patient's knee joint. A point probe captures the geometry of a bony surface of the patient. A computing module receives the location data and geometry data, and determines a surgical plan including parameters of a graft tunnel.

  • Publication number: 20210275258
    Abstract: A cut guide assembly (600) and a system for mounting assembly on a patient are described. The system includes an ankle clamp (525), an alignment guide (530) configured to be removably attached to the ankle clamp, and the cut guide assembly. The cut guide assembly includes a cut guide (535) and a position tracker (200). The cut guide includes a receiving feature (605) configured to removably attach to at least a portion of the alignment guide, a locking mechanism (610) configured to lock the receiving feature to the at least a portion of the alignment guide, and a plurality of pin receptacles (620), each of the plurality of pin receptacles configured to receive a bone pin (540) configured to affix the cut guide to a patient's bone. The position tracker configured to be affixed to the cut guide when the cut guide is affixed to the patient's bone.

  • Publication number: 20210204963
    Abstract: A system for tracking resection planes during a surgical procedure includes a cutting block and a position tracker. The cutting block is configured to be mounted on an anterior surface of a bone during the surgical procedure. The cutting block comprises at least one slot configured to position a resection tool during the surgical procedure. The position tracker is configured to be directly attached to the cutting block after the cutting block is mounted on the anterior surface to allow positional tracking of the cutting block by a tracking device during the surgical procedure.
